An Efficient of Iodine Functionalized Magnetic Graphene for Acetylation of Sugar Derivatives

A simple and clean synthesis of per-O-acetylation carbohydrate derivatives has been reported using a stoichiometric quantity of acetic anhydride under solvent-free conditions in the presence of I@GO@CoFe2O4 nanocomposite as an efficient magnetic nanocomposite. The efficient three-step preparation procedure of the magnetic nanocomposite included the synthesis of graphene oxide (GO) that is added to a mixture of CoFe2O4 nanoparticles, followed by doping iodine into magnetic graphene oxide sheets by mixing potassium triiodide-choline chloride (KI3:ChCl) deep eutectic solvent (DES) as an iodine source. The anchored phases are characterized by SEM, XRD, FT-IR. As well as the aesthetically appealing structure of Per-O-acetylation of Sugar Derivatives is well consistent with the measured spectroscopic data.
